transmitted from the other side.    NRC is a single number ranging between 0 – 1.0

measured at frequency 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz and 4000Hz  under ASTM C 423

5. Ceiling Attenuation Class (CAC)

CAC is the ability of a ceiling tile to prevent the transmission of sound between rooms with a

common ceiling space.    Therefore, it rates a ceiling’s efficiency as a barrier to airborne sound

transmission between adjacent closed offices under ASTM E 413 standard.
